So I have been researching some milage runs to complete with the 2x europe promo and have an intresting senario.

I can book PHL-MUC roundtrip and MUC-PHL round trip for under $1000.

Trip A
PHL-ATL-MUC Depart 2/1 1Arrive 2/12
Trip B
MUC-ATL-PHL Depart 2/12 Arrive 2/12
Trip B
PHL-ATL-MUC Depart 2/17 Arrive 2/18
Trip A
MUC-ATL-PHL Depart 2/18 Arrive 2/18

I want to fly all the ticketed segments - typically back-to-back ticketing is used get a lower price on the return segment and then not using the rest of the ticket.

I found another route that was a little more than $1200 but it's a KILLER
PHL-ATL-LAX-HNL-LAX-ATL-MUC-ATL-LAX-HNL-LAX-ATL-PHL that nets over 30k miles booked as PHL-HNL and HNL-MUC. It takes 7 days to complete - and would be completely 'legal' - but I dont think I could make it that long!
